MONTROSE — A woman charged in the deaths of two young sisters whose bodies were found on a southwestern Colorado farm has been convicted.

The Montrose Daily Press reports Ashford Archer was found guilty Thursday of two counts of fatal child abuse and being an accessory to a crime for the deaths of 10-year-old Makayla Roberts and 8-year-old Hannah Marshall.

Investigators believe the sisters were dead for several weeks before the bodies were found in September 2017 on a farm outside Norwood. Archer was part of a religious group that moved to the property earlier that year, and prosecutors said the girls were banished to a car because they were thought to have been impure.

Denver Sheriff Patrick Firman's resignation this week culminated years of mistrust from deputies and community activists, who said that was the price of filling the position with a man who was never the right person for the job.
